Jason is a person who I like without limit. He is guiding us through the theories that exist. Nothing more. And as such you should listen to him as the most efficient way to get current. His plan seem to be in the fold .... good plan .... anyways he read up on everything he is saying.

Thanks! That is the plan! My hope is to get the entire Cosmology course done before I go to the Winter AAS meeting in January 2025.

@@JasonKendallAstronomer I listen to you and other channels through sleepless nights cause I have some medication but my brain refuse to sleep. ANYWAYS forget that. My interest lately has been how everything has been established. The lewit cephids the parallax as a technician and a perfectionist eliminate the errors. So here come Jason and tell us how hard they are trying.

maybe Jason as a side show can delve into what pawed the way to these discoveries. It is all technical I am sure but as a technician I am not afraid, Cause I am trying to figure out why they know what they know,

23:05 I have problems with understanding Photons! is a single Quant_of_Pht really a travelling packet of ELM_vibration in a "line" or is it a 3D_Sphere, expanding at c and "gaining" direction only at Time of Detection/Absorption? But then again how to explain Lasers? (which always are a multitude od Quanta)

I hadn't realized you just recorded these videos from your lectures following a textbook you do it so well. You're passion towards both astronomy and educating really shines through... such a wonderful combination...

Wow, thank you! Yes, I'm working on the entire textbook.

I am becoming increasingly convinced of higher quarks being found in the quark/gluon soup found at the cores of neutron stars. Their energy being sustained by the gravitational contraction as they ecrete matter at the surface. There is however, only theories, no way of ever proving it. But like the dubious, mathematical failure of the singularity at the cores of BH's, it makes most sense to me if there were. Great lecture Mr. Kendall, thank you.

Probably not, although I don't pretend to understand their reasoning most physicists seem to be pretty convinced that there are 6 and only kinds of Quark and 6 Leptons.

Excellent stuff. Professor Kendall, is there a better explaination for dark matter that doesn't involve inventing a band-aid material? Could it be a magnetic process or something similarly non-arcane?
@JasonKendallAstronomer
@JasonKendallAstronomer 3 месяца назад
Nope. The energy density must be something like matter, but that doesn’t do light. That’s the conclusion of CMB studies.
@JasonKendallAstronomer
@JasonKendallAstronomer 3 месяца назад
Also, remember Haldane’s quote: “The universe is not only stranger than we imagine, it is stranger than we can imagine.” The wild ad hoc nature of dark matter is just a glimpse into this strangeness. Nature has no obligation to fit our common sense, which only works for our little corner of the planet Earth.

Excellent ! Re dark matter.. Neil Turok suggests that the dark matter particle is a heavy right handed neutrino (as a result of one of the left handed neutrinos being zero mass ). If the zero mass is established in next few years he could be onto something !!

@@pressureswitch I’ve always liked it, but idk about the details of how heavy or what temperature it would be, and whether it’s ruled out by cosmological considerations. As far as a standard model extension, it makes perfect sense unless some weird renormalization infinity ruins it.
